1
Q
Compared to adults, children are at a greater risk for fluid and electrolyte imbalance. Why??
A
- A greater body surface area
- A higher percentage of total body water
- A greater potential for fluid loss via the gastrointestinal tract and skin
- Increased incidence of fever, URI, and AGE
- A greater metabolic rate
- Immature kidneys that are insufficient at excreting waste products
- Kidneys have a decreased ability to concentrate urine
- Inability to verbalize thirst
